After dimintx (1)/,write a number whose specific shaping is not less than 0.

Dimensional accuracy (1)

For security reasons, you can allocate a larger array memory. If you are uncertain about the number of arrays, you can use ReDim.

take for example

m= 10

ReDim a(m)，b(m)

Yes, where m can be taken according to the actual situation, such as m=UBound(MyArray), so there will be no problem of crossing the border.
